re: Chalk up a 'W' for prior infection immunity: Israeli study shows it 6X-13X more effective

We'll have to wait for peer review to see if this goes the way of the fraudulent ivermectin "study."

This preprint is a bit of a bombshell.

The results point to natural infection affording longer-lasting and stronger protection against infection, symptomatic disease and hospitalization due to the SARSCoV2 Delta variant than vaccine-induced immunity.

The results also point to one dose of BioNTech/Pfizer mRNA vaccine administrated post-infection providing marginally higher protection than immunity due to prior infection alone.

The study has a huge sample size and is the largest of its type to date. The analyses look competent to me. There are likely subtle biases in the data, but given the clearcut results, the patterns are in all likelihood genuine.

There have been previous results pointing in that direction. Of all Covid19 cases in July 2021, 99% had never been infected and 78% never vaccinated, and this despite far many more people having been vaccinated than infected by SARSCoV2 in the UK.
